The Minnesota Vikings have a better idea about how to finish preparing Adrian Peterson and his surgically repaired left knee for the season.

The plan, simply, is more practice. Coach Leslie Frazier said Tuesday he changed his mind about handing the ball to his recovering star running back in a preseason game. Frazier originally said he wanted Peterson to experience the full contact of such a setting before the real season begins, but he has backed off.

Peterson actually agreed this time. ‘‘My goals are still the game,’’ he said. ‘‘I look forward to being back the first week’’ of the regular season.

That Peterson, a fierce, relentless competitor who has lobbied for more playing time seemingly since the day he was drafted, was satisfied with the decision was as sure a sign as any the Vikings are making a wise move.

‘‘There are no setbacks. That’s not the reason we’re doing it,’’ Frazier said. ‘‘We just feel like more time with him in practice with some of the things that we’re doing and the progression of getting him ready for the season, it’s the right thing to do.’’

The opener is Sept. 9 against Jacksonville, and Frazier again declined to guarantee that Peterson will be cleared to play that afternoon.

Titanic holdout

Maurice Jones-Drew’s holdout appears far from over. His agent, Adisa Bakari, told The Associated Press that the Jacksonville Jaguars running back is upset with owner Shad Khan’s recent comments about his client’s 27-day holdout.

‘‘Maurice wants to play for an organization that wants him and for an owner who respects him and values what he brings to a team — on the field, in the locker room, and in the community,’’ Bakari said.

Asked Tuesday whether he would trade Jones-Drew, Khan said he is ‘‘not going to get into all the theses and hypotheses.’’ Khan added that Jones-Drew is ‘‘a great player, and we would love for him to be back.’’

Last week, however, Khan said his absence ‘‘doesn’t even move the needle’’ in terms of stress. Khan reiterated his stance Tuesday by saying, ‘‘This is not a team about one person.’’ His message to Jones-Drew? ‘‘Train’s leaving the station. Run, get on it,’’ Khan said.

Bakari made it clear that those statements don’t sit well with Jacksonville’s biggest star.

Jones-Drew wants a new deal after leading the NFL with 1,606 yards rushing last season. He has two years remaining on a five-year, front-loaded contract worth $31 million. He is scheduled to make $4.45 million this season and $4.95 million in 2013.

The NFL announced the Jaguars will play one home game in London for four consecutive seasons beginning in 2013. NFL commissioner Roger Goodell, who joined Khan for the announcement, reaffirmed his commitment to expanding to multiple games in England and eventually establishing a franchise there.

Vick banged up

Michael Vick has needed four medical tests through two preseason games and has completed only four passes. That is an ominous sign for the Philadelphia Eagles.

The three-time Pro Bowl quarterback left Monday’s win against the Patriots after injuring his ribs on his sixth play. He lasted just six plays against Pittsburgh before being forced out by an injured left thumb.

X-rays on Vick’s ribs at the stadium were negative, and an MRI and CT scan on Tuesday revealed he has no broken bones or fractured cartilage. Vick has a contusion of his ribs and of the soft tissue surrounding it. He also needed X-rays on his thumb, and those tests were also negative.

It is likely Vick won’t take another snap until the Eagles open the regular season at Cleveland Sept. 9.

‘‘If he didn’t play again [in the preseason] then he’d be OK,’’ Eagles coach Andy Reid said. ‘‘I would tell you I’d probably like to see him play a little bit more, but he’s got enough experience. We’re not talking about a rookie. I think he’ll probably be OK.’’

Portis retires

Clinton Portis is announcing his retirement — nearly two years after he played his last NFL game. Portis and Washington Redskins owner Dan Snyder will hold a news conference Thursday in Ashburn, Va.

Portis played two seasons with the Broncos and seven with the Redskins. The Redskins cut him after a torn groin muscle ruined his 2010 season.

He was unable to find another team and ends his career 77 yards shy of 10,000, No. 27 on the NFL’s all-time list.

Rogers might return

Despite developing a blood clot in his left leg a little more than a week ago, there is a chance Giants defensive tackle Shaun Rogers might play this season. Coach Tom Coughlin said that the 12-year-veteran got a second opinion about his injury, and the team has ‘‘a ray of hope’’ that Rogers will be able to get back on the field . . . Steelers linebacker James Harrison is optimistic his left knee will be ready in time for the season opener against Denver. Harrison had a minor procedure on the knee last week and hasn’t practiced during training camp . . . Jets nose tackle Kenrick Ellis will not be suspended by the NFL after the league completed its review of his legal situation following his guilty plea to misdemeanor assault and battery. Ellis was sentenced to 45 days in a Virginia prison in May for his part in a fight while in college at Hampton University in 2010 . . . Jets right tackle Wayne Hunter was excused from practice for what the team called a ‘‘personal reason’’ and is expected back Wednesday . . . Former Jets safety Jim Leonhard practiced for the first time with the Broncos since undergoing a right knee operation in December.
